ABSTRACT:

The dosing plunger movement is controlled in one direction by a fluid pressure and in the opposite direction by the liquid which is under pressure. Diaphragm valves are formed on both faces of the dosing element through cooperation among the dosing element, an interposed sealing element, and a connecting plate.
